Abstract
Purpose
There are many year-round modifiers of chronic rhinosinusitis (CRS). However, it is unknown whether there are seasonal variations in the sinonasal symptom burden of CRS.
Methods
This was a retrospective cross-sectional study of sinonasal symptom burden measured using the 22-item Sinonasal Outcome Test (SNOT-22) and its four associated nasal, sleep, ear/facial discomfort and emotional subdomains in 1028 individuals with CRS. The season (winter, spring, summer or fall) when the SNOT-22 was completed was recorded. Regressions, controlling for clinical and demographic characteristics, were performed to seek association between season of the year and SNOT-22 total and subdomain scores.
Results
The mean SNOT-22 scores were 37.4 for those individuals completing their SNOT-22 in the fall, 40.5 in the winter, 37.4 in the spring and 36.0 in the summer. There was a statistically significant association between higher SNOT-22 scores and completing the SNOT-22 in the wintertime (adjusted β = 4.08, 95% CI 0.74–7.42, p = 0.017). When seeking association between season and SNOT-22 subdomain scores, wintertime was associated only with higher emotional (adjusted β = 0.48, 95% CI 0.14–0.81, p = 0.006) and sleep (adjusted β = 2.23, 95% CI 0.54–3.91, p = 0.010) subdomain scores. Examining individual SNOT-22 items, these associations were due to more symptoms related to depressed mood (“sad”) and psychomotor retardation.
Conclusion
There are seasonal variations in symptom burden of CRS patients, independent of aeroallergen hypersensitivity, with the greatest increase in baseline CRS symptomatology during the winter. This finding was most strongly associated with increased emotional symptomatology and depressed mood.
